Frequently Asked Questions

Is this hinge suitable for fire doors? Yes. The QS4415 carries European CE certification and is stamped accordingly, making it compliant for use on fire-rated doors in residential and commercial buildings.

How many hinges do I need per door? Most standard interior doors require 2 hinges. Fire doors and heavier doors typically require 3 hinges. Check your door manufacturer’s specification or local building regulations for the required number.

What is the difference between 304 and 316 stainless steel for hinges? Both grades offer excellent corrosion resistance. The practical difference in staining and pitting between 304 and 316 is negligible in most environments, making 304 an excellent value choice.

What does ball bearing mean on a hinge? A ball bearing hinge contains small steel balls between the hinge knuckles, reducing friction and allowing the door to swing smoothly and quietly. Ball bearing hinges are more durable than plain bearing hinges under heavy use.

Is this hinge sold as a single or a pair? It is sold as a pair — two hinges per pack.
